Sunscreens contain filters that reflect or absorb UV rays. There are two main types of filters:
- Organic. Organic filters absorb UV radiation and convert it to a small amount of heat. Examples include cinnamates, salicylates and benzophenones.
- Inorganic. Inorganic filters reflect and scatter UV radiation. Examples include titanium dioxide and zinc oxide. Inorganic sunscreens are typically less irritating to skin.
Sunscreens might also contain or be combined with:
- Insect repellent. Experts recommend using separate sunscreen and insect repellant products. Sunscreen needs to be applied generously and often, while insect repellant should be used sparingly and less frequently.
- Cosmetics. Some moisturizers, makeup and after-shaves contain sunscreen. While convenient, these products need to be regularly reapplied to continue providing protection.
